The Bhoot Jolokia,a chilli cultivar, also known as ghost pepper is cultivated only in the Northeast India in the states of Assam, Nagaland and Manipur. Pest complex study of Bhoot Jolokia was carried out at Experimental Farm, Department of Horticulture, Assam Agricultural University, Jorhat, Assam during 2013-2015. The major insect pests that attack Bhoot Jolokia were the sucking pests viz., aphids, Aphis gossypii Glover; Thrips, Scirtothrips dorsalis Hood; Whitefly, Bemisia tabaci Gennadius and Leafhopper, Amrasca biguttula biguttula Ishida. Other pests include Cutworm, Agrotis ipsilon Hufuagel and Flea beetle, Monolepta signata Oliveir. During the period of investigation, altogether five species of coccinellid predators were encountered in the ecosystem viz., Coccinella transversalis F., Cheilomenes sexmaculata F., Brumoides saturalis F., Micraspis discolour F. and Harmonia dimidiata F. during the second year of investigation. The correlation studies indicated that A.gossypii, S. dorsalis , B. tabaci , A. biguttula had a negative correlation with maximum and minimum temperature, wind speed and rainfall. However, morning and evening relative humidity showed a positive correlation for all the sucking pests during both the years of study.
